SHEET-CONVEYING MACHINE.

Specification of Letters Patent.

Patented May 3, 1910.

Application filed August 13, 1909. Serial No. 512,708.

To all whom it may concern:

Be it known that I, Tanno'r C. DEXTER, a citizen of the United States,residing at Pearl River, county of Rockland, State of New York, haveinvented certain new and useful Improvements in Sheet-ConveyingMachines, of which the following is a specification.

The present invention is an improvement upon the sheet conveyingmechanism covered by an application filed by me February 5th, 1909,Serial No. 470,296. In the inachine of said application, the sheetconveying surfaces for carrying successive sheets of paper from anautomatic paper feeding machine to a printing press or other machinedesigned to operate upon them are driven by a frictional drivingmechanism comprising a disk and an automatically adjustable wheel whichis intermittently moved inwardly and outwardly over the surface of thedriving disk for the purpose of effecting the rapid movement of thesheets during the main part of their travel from the feeder to the ressand the slowing down and quiet de ivery of the sheets to the ga es ofthe press.

In mac lines of this type, it will be under stood that sheet engagingand conveying devices retain hold of the sheet during the entire travelof the sheet from the feeder to the press, a feature of very greatimportance in accurately feeding sheets at the rapid speed required forprinting machinery of today.

In my present invention, I have devised a modified frictionally drivenslow down feeding mechanism in which change of speed of the sheetconveying mechanism is effected by providing on the driving shaft, twofriction wheels mounted upon an adjustable section of the shaft andcontrolled by mechanism which intermittently and alternately moves saidfriction wheels into engagement with the frictional driving disk, one ofsaid wheels engagingthe disk near the outer periphery for effecting therapid motion of the sheet conveying mechanism, while the other of saidwheels engages the driving disk near its center of rotation foreffecting the slow movement of the sheet conveying mechanism.

In order that my invention may be fully understood, I will firstdescribe the same with reference to the accompanying drawings, andafterward point out the novelty more particularly in the annexed claims.

In said drawings: Figure 1 is a side elevation of my improved sheetconveying mechanism representing it in operative position between anautomatic feeding machlne and a printing ress. Fig. 2 is a lan view ofthe same. 1 igs. 3 and 4 are en arged detail plan views showing theadjustable frictional driving mechanism in its two positions.

CHARLES DRUCK, or SHAW, OREGON.

COMBINATION-TOOL.

Specification of Letters Patent.

Application filed July 2, 1909.

To all whom it may concern:

Be it known that I, CHARLES DRUoK, a citizen of the United States,residing at Shaw, in the county of Marion and State of Oregon, haveinvented new and useful Improvements in Combination-Tools, of which thefollowing is a specification.

The present invention relates generally to improvements in combinationtools, and more particularly in the head or carrier to which the toolproper is connected, and its object, broadly stated, comprehends theproduction of an extremely simple and effective tool-head constructed insuch a manner as to permit the attachment thereto of various forms ofhandles, and of tools, so that the implement may be utilized as aratchet or a pipe wrench, or as a drill or auger.

The invention further resides in the production of a notched collararranged for cooperation with the pair of dogs which in turn engage theratchet, the collar being fitted upon the stem of the cap wherein saiddogs are pivoted and being so constructed as to act upon either or bothof the dogs and hold the same in inoperative position.

Briefly described, the tool-head, in which, as above stated, theinvention primarily resides, comprises a threaded split shank betweenthe legs of which is frictionally held a threaded cross-bar, held inplace by means of a pair of collars disposed upon opposite sidesthereof. The shank is further formed with a reduced threaded stem towhich is attached the above-mentioned cap, the latter inclosing theratchet rigidly fastened to said stem and carrying the two dogs whichengage the ratchet. When the implement is operated as a wrench, the jawsare attached to the arms of the cross-bar. The operating handle,according to its nature, may be connected either to the stem or to thecap, and the free end of the shank is designed for connection with achuck, in which latter a bit or similar tool may be inserted.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein:

Figure 1 is a side elevation of the im proved combination tool designedfor employment as a ratchet wrench. Fig. 2 is an enlar ed detail view ofthe tool head and its atten ant parts, the view being partly inhorizontal section and partly in plan. Fig. 3 is a side elevation,partly in section, of

. Fig. 2. Figs. 4 and 5 are detail views,

respectively, of one of the wrench jaws, and of the notched collar. Fig.6 is a side elevation showing the implement adapted for operation as adrill and having a reciprocatory handle, portions of which are brokenaway. Fig. 7 is a side elevation of the implement adapted for use as aratchet drill. Fig. 8 is a side elevation of the implement convertedinto a pipe wrench. Fig. 9 is a side elevation of the implement designedfor operation as a drill by a further modified arrangement of parts, thesupplemental handle employed in this connection being likewise shown.

Reference being had to said drawings, and more articularly to Figs. 1 to5, inclusive, A designates in a general manner the improved tool head,in which the principal features of the invention are presented, and Bthe handle by means of which the head is rotated.

The element A comprises essentially a member 1 having a threaded shankor body portion 2 and a reduced stem 3 formed in axial alinemcnt withthe first-mentioned portion, said shank or body ortion being split orbifurcated longitudina ly throughout the greater portion of its length,as indicated by the numeral 4. Between the legs 5 so formed is passed across-bar 6 which is held against endwiso movement by the springpressure of the legs, and in adjusted position by means of a pair ofmilled locking collars 7 and 8 disposed upon opposite sides thereof. Thetwo arms of the cross-bar are designed to be inserted through thetransverse passages 9 formed in the jaws 10 and 11, each of which has aportion of one of its faces inclined and serrated, as indicated by thenumeral 12. The two jaws are each formed with an additional passage 13which is arranged at right angles to and intersects the correspondingfirst-mentioned passage. Each passage 13 is designed to receive a millednut 14 which is threaded upon the corresponding arm of the cross-bar andis adapted to be turned thereupon, thereby effecting the movement of thejaws with respect to each other. Access to the nuts is facilitated bycutting away a portion of the side faces of the j aws. Upon the shoulder15 which results from the formation of the reduced stem 3, there rests acap 16 having a transverse opening through which the stem projects. Thecap is further provided with a transverse passage 17, which is formed atright angles to and intersects the stem opening, and with a lateralextension or stem 18, having a pair of steps 19 and 20 of differentdiameters, the smaller step being threaded.

Within the passage 17 is disposed a ratchet 21 rigidly secured in anysuitablemanner to the stem, the teeth of the ratchet being normallyengaged by a pair of dogs 22, likewise pivoted Within the passage, underthe influence of a pair of springs 23. These dogs are arranged onopposite sides of the ratchet, and the springs which bear against thetail portions thereof are arranged in seats opening into the passage.The collar 24, shown in detail in Fig. 5, is fitted loosely upon thestep 19, and is designed for cooperation with the dogs, across whosetail portions the side wall of the collar extends. This wall is formedwith two notches 25 and 26 of different widths. When either notch isopposite one of the dogs, the tail portion of that dog will moveoutwardly under the influence of the adjacent spring 23, so as to engagethe other end thereof with the ratchet, but when the solid portion ofthe wall is in contact with the tail portion of either dog, such portionis forced inwardly, and the dog thereby rendered inoperative. Thus itwill be apparent that either or both of the dogs may be renderedoperative or inoperative, according to the use to which the implement isput. l/Vhen operated as a ratchet wrench, only one of the dogs isoperative, as will be understood. The collar is held againstdisplacement by means of a washer 27 fitted upon the step 20. The handleB, shown in Fig. 1, comprises essentially, two members 28 and 29. Themember first mentioned is L-shaped, and has one arm thereof providedwith a grip 30, and the other arm with a breastplate 31, the latterelement being removably attached to the bent terminal of thecorresponding arm by means of a sliding catch 32 operated by aspring-pressed finger-lever 33 pivoted to the stem of the breast-plate.The member 29 of the handle is in the form of a hollow rod or tube whoseopposite ends are internally threaded. The inner end of this member isdesigned to receive a reduced threaded extension 34 formed upon thelaterally-bent free end of the grip-carrying arm of the member 28, whilethe outer end thereof receives the threaded step 20. It will thus beapparent that the connection of the tool-head A to the handle iseffected by means of the cap 16, and since the latter carries the twodogs which engage the ratchet secured to the stem 3, the head, and withit'the jaws, may be either rotated or oscillated, according to themanner in which the handle is operated. Further description of this formof the in- V vention is considered unnecessary, it being noted, however,that the invention resides primarily in the construction of thetoolhead, and in the manner in which the same is connected to anoperating handle, rather than in the employment of any particular formof handle in connection with the toolhead, since the type of handle useddepends solely upon the use to which the implement is intended to beput, and upon the manner in which it is to be operated. For instance,when it is desired to use the implement as a drill, the handle B shownin Fig. 6 is employed in lieu of the handle B, the jaws 10 and 11 aredetached from the cross-bar 6, and a chuck 35 is attached to the free orouter end of the shank 2. The member 29 is disengaged from the member 28and is utilized as a brace or supplemental handle. The main handle Bconsists of two tubular members 36 and 37, having a pin-and-spiralgrooveconnection of the usual type with each other, so that when the member 36is moved endwise by hand, a rapid rotary movement will be imparted tothe head A and to the chuck, both dogs being held against operation byturning the collar 24 in the proper direction. The outer end of theinner handle member 37 is formed with an internally-threaded collar 38designed to receive the free end of the stem 3, said collar having atooth 39 formed on its outer surface. Both ends of the outer handlemember terminate in internally-threaded collars 40 and 41, the latter ofwhich has a notch 42 cut therein.

When it is desired to transform the implement into a ratchet drill, thetwo members of the handle are locked together by engaging the tooth 39in the notch 42, after which the handle is detached from the head,reversed, and subsequently attached to the member 29, the threaded end43 of which is fitted in the bore of the collar '40. See Fig. 7. Thebreast-plate 31 is then attached to the free end of the stem 3. In thisconstruction, the interlocked members 36 and 37 and the member 29, unitein forming the handle B Either dog is free to operate upon the ratchet.

l/Vhen the implement is to be operated as a pipe wrench (Fig. 8), thecross-bar 6 is shifted lengthwise through the bifurcation 4 until thelength of one arm is sufiiciently great to permit 'the' attachment ofboth the jaws 10 and 11 thereto, the jaws being so arranged with respectto each other that the inclined gripping face 12 of one jaw is oppositethe plane gripping face of the other jaw. The rigid compound handle B isemployed, and the collar 24 is turned in the proper direction to releaseboth dogs and leave them free to operate.

In Fig. 9, the reciprocatory handle 13 and the chuck 35 are employed,and the handle member 29 and the jaws are omitted. The handle isoperated by the application of a direct downward pressure upon themember 36, the upper end of which is designed to receive the stem of aT-shaped supplemental handle 44.

The operation of the various forms of the invention is thought to beobvious from the foregoing, and an extended description thereof isaccordingly omitted. It will be seen, however, that the cross-bar 6 isretained in all forms, irrespective of whether the implement be utilizedas a Wrench or drill. In the former instance, this element carries thetwo jaws, and in the other instance, it may serve as a brace, to permitthe bit or other tool to be loosened prior to its detachment from theWork.

What is claimed is:

1. In an implement of the class described, the combination of atool-head comprising shank and stem portions, the shank having alongitudinal slot formed therein; a cross-bar inserted through said slotand arranged for endwise and sidewise adjustment bodily in the same;means carried by said shank and arranged upon opposite sides of saidbar, for retaining the latter in adjusted position; and an operatinghandle connected with the stem of the tool-head.

2; In an implement of the class described, the combination of atool-head comprising a stem and a threaded longitudinally-slotted shank;a cross-bar inserted through said slot and arranged for endwise andsidewise adjustment bodily therein; a pair of collars threaded upon theshank on opposite sides of said bar, for retaining the latter inadjusted position; and an operating handle connected with the stem ofthe tool-head.

3. In an implement of the class described, the combination of atool-head comprising stem and shank portions, the shank having alongitudinal slot formed therein; a cross-bar inserted through said slotand arranged for endwise and sidewise adjustment bodily therein; meanscarried by said shank and arranged upon opposite sides of said bar, forretaining the latter in adjusted position; a cap mounted upon the stemand formed with a pair of intersecting passages through one of whichsaid stem extends; a ratchet secured to said stem and arranged within athe other passage; a pair of dogs mounted within said other passage andarranged for engagement with said ratchet; a shiftable member carried bysaid cap and arranged for movement into position to release or engageeither or both of said dogs; and an operating handle connected with saidcap.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit nesses.
